This is not quite how it works. Note that the LGPL is itself
constructed as an exception to the GPL. When you submit a modification
of a work that is licensed under the LGPL+exception that modification
is licensed the same way.

The default LGPL requires that you either (a) use only a dynamic
library or (b) release your entire app as (L)GPL.  The static linking
exception does what it says, it lets you link libzmq into static
executables. This was originally required for iOS but also used by
people on other systems.

Removing this would be damaging to use of 0MQ, and would break the
existing contract we have between contributors. Further you cannot
remove it for any derived work, only 100% new works.
